“数形结合”和“运动变化”是小学数学学习中重要的思想方法,在小学阶段开启学生数学思考的大门,几何画板不失为一个简单实用的工具。几何画板可以做出各种神奇的图形,能很好地把数和形的潜在关系及其几何图形变化过程动态形象地显示出来,随时观察到各种情况下的数量关系及其变化。另外,几何画板还可制作出各种动态图像模型,具有PPT无可比拟的作用。因此,几何画板是数学教学的催化剂,我们要学会妥善使用。
“Shape combination ” and “Movement ” is an important way of thinking in primary school mathematics learning. It opens the door of students’ mathematical thinking in primary school. Geometrical drawing board is a simple and practical tool. Geometric drawing board can make a variety of magical graphics, can well be the number and shape of the potential relationship between the geometric changes in the process of dynamic display, at any time observe the quantitative relationship between the various circumstances and changes. In addition, geometric drawing board can also produce a variety of dynamic image model, with PPT unparalleled role. Therefore, the geometric drawing board is the catalyst of mathematics teaching, we must learn to use properly.
